Well its the write to SIMR that needs a sync before enabling external interrupts, not the sipnr variable. > So I think there should be a time delay when we do mask&ack(&following > operation maybe). Don't agree, I believe the missing sync is a bug. I talked a Motorola FAE yesterday and he says the same thing. It doesn't really matter if you have the 8260 as a slave or not. What does the maintainers of this code (Tom Rini?) think about it? Thanks, Hans ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
